It was a very comfortable electoral college win, which is what matters. The Republicans have only won the popular vote once in 30+ years. I think Harris gets a fairly blowout win in terms of popular vote, but merely a comfortable one at the electoral college. In the neighborhood of 2020...
That wasn't a comfortable win for Kennedy though - about 0.2% in it, about 110,000 votes. Although I am also more optimistic about Harris.
